Our Founding Scripture - Chronicles  9:21

21 And later Zechariah son of Meshelemiah had been responsible for guarding the entrance of the tabernacle.
22 In all, there were 212 gatekeepers in those days, and they were listed by genealogies in their villages.  David and Samuel the seer had appointed their ancestors because they were reliable men.
23 These gatekeepers and their descendants, by their divisions, were responsible for guarding the entrance to the house of the LORD, the house that was formerly a tent.
24 The gatekeepers were stationed on all four sides—east, west, north, and south.
